Several persons have expressed the wish to view our schematics for various versions LClock.
Therefore i have decided to make them all available here on diyaudio.com, so you can build them freely as you like.

To make it easier to oversee everything i will post the 4 basic schematics in cronological order. (Lclock 1, Lclock 2/C2, Lclock XO/XO2, Lclock XO3).

But please bear with me, i have to find them, check them and brush them up a bit as i go, so it might take a week or two before all schematics are posted.

Peranders: You are right, series resonant mode is better than parallel resonant mode, because the impedance of the crystal in series mode is much lower than in parallel mode. This leads to lower noise sensitivity.
And inside of a CD or DVD player there is plenty of digital noise to disturb the oscillator.

In the two above early LClock's we used parallel resonant mode, as it is the simplest to work with. Later on it will change to series resonance mode.
